When can you plant in Slate Springs, MS?
Around 03/28 is the usual last spring frost, about 212 days away. The first fall frost typically arrives around 11/05, about 223 frost-free days later.
The USDA Plant Hardiness Zone Map puts Slate Springs in Zone 8a (10 to 15°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

Why 03/28 isn't a guarantee
03/28 is the middle of 30 years of NOAA records, not a promise. Plant by 03/06 and you're betting against frost in roughly 9 years out of 10. 04/11 is the safer bet, historically only a 1-in-10 chance of frost that late.
